Proposed AASHTO Practice and Tests for Process Control and Product Acceptance of Asphalt-Treated Cold Recycled Pavements


Diefenderfer, Boz, Habbouche, Jones, Hand, Bowers & Flintsch


This is the final report for NCHRP 9-62 where the authors developed a short pin raveling test to determine when a CCPR pavement has sufficiently cured to allow opening to traffic and a long pin test to determine when the pavement has cured sufficiently to place the wearing surface. The authors have recommended additional field verification of the proposed test methods and threshold values.
